It is recommended to replace it every three months or so. The main reasons for replacing brush heads are:
1.A healthy brush head has better cleaning ability.
2. The cleaning ability of the toothbrush will decrease after long-term use, and the bristles will gradually wear out over time and easily adhere to dental plaque.
3. After three months, the bristles will be deformed, and the damaged bristles will easily breed a large number of bacteria.
